Which classes are subclasses of the Unchecked class in Java?

The heirs of the Unchecked class in Java are classes that inherit directly or indirectly from RuntimeException.

Examples:

• NullPointerException
• ArrayIndexOutOfBoundsException
• IllegalArgumentException
• IllegalStateException
• ClassCastException
• UnsupportedOperationException
• ArithmeticException

These exceptions do not require explicit handling (no need to catch or declare in the method signature). They most often indicate errors in the program logic that can be prevented during development.
